How good is the iphone 4 battery life when cellular data is turned off but using Wi-Fi?
I don't own an iPhone, but I can't see why you would think the battery life would be different depending on the type of data your using.
Depending on the actual usage of data rather than the wi-fi over cellular data.
- Will i be charged for texts on iPhone even though i turned off cellular data and enable 3G? I have turned off my cellular data and 3G believing that everything of texts web browsing etc. Is all based on Wi-Fi. I know imessage won't charge me even though i'm on Wi-Fi. However if i were to text someone who does not have an iphone and it isn't imessage will i still be charged? Because sending messages to them works with my cellular data and 3g off but will i be charged or even charged more since it is off?
